Effect of Ultraviolet Light Aging on Fatigue Properties of Asphalt

Abstract:

The ultraviolet aging effects on fatigue properties of asphalt were studied by using Dynamic Shear Rheometer (DSR). The low-temperature fatigue performance of asphalt has been tested in this paper with the strain-controlled mode of DSR. The samples were compacted under the temperature of 10°C and the constant strain of 2.0% in strain-controlled mode fatigue test. And the results showed that ultraviolet aging decreases the fatigue life-span of asphalt significantly.
